(-8,-4)&(2,-9) fint the distance between each pair of points

Mathematics

Makovka662 [10]3 years ago
7 0

Answer:

5 \sqrt{5}

Step-by-step explanation:

We want to find the distance between (-8,-4) and (2,-9).

We use the distance formula:

d =  \sqrt{ {(x_2-x_1)^2} +(y_2-y_1)^2 }

We substitute the coordinates to get:

d =  \sqrt{ {(2- - 8)^2} +( - 9 -  -  4)^2 }

We simplify to obtain:

d =  \sqrt{ {(2 + 8)^2}+( - 9  + 4)^2 }

Add the numbers within the parenthesis to get:

d =  \sqrt{ {(10)^2}+( -5)^2 }

Find the squares of the numbers under the radical

d =  \sqrt{ {100}+25}

d =  \sqrt{125}  = 5 \sqrt{5}

Hitman42 [59]

-1.2x - 6.5x ≤ 2.3x + 5

-7.7x ≤ 2.3x + 5

≤ 10x + 5

-5 ≤ 10x

-1/2 ≤ x

x ≥ -1/2

The members of a cooking club are making cakes, which they will sell at a street fair for $8 apiece. It cost $30 for a booth at
Olin [163]

They need to sell 5 pieces to cover their expenditures (have a profit of zero).

<h3>How many cakes will they have sold?</h3>

We know that the costs are:

  • $30 for the booth at the fair.
  • $2 for each piece of cake they sell.

And the revenue is:

  • $8 for each piece of cake.

So, the profit (the difference between the revenue and the cost) for selling x pieces is:

p(x) = $8*x - $2*x - $30

p(x) = $6*x - $30

We want to find the value of x such that p(x) = 0, then:

0 =  $6*x - $30

x = $30/$6 = 5

They need to sell 5 pieces to cover their expenditures (have a profit of zero).
